CHARGING DEVICE.

Specification of Letters Patent.

Application filed December 24, 1909. Serial 'No. 534,864.

To all whom 'it may concern:

Be it known that I, CHARLES W. LUMMIs, a. citizen of the United States,and a, resident of Camden, Camden county, New Jersey, invented certainImprovements in Charging Devices, of which the following is aspecification.

My invention relates to means for feeding coal or other material to gasproducers,- cupola furnaces and structures of a similar character, andthe object of my invention'is to provide means for insuring anevenfeedterial.

The usual method of feeding coal togas producers, furnaces and the like,is to provide a magazine or hopper, which may be and distribution of thefuel or other macontinuously rotatable or havea rotatable bottom intowhich the coal is fed and from which the coal is discharged, with asuitable distributing device carried by or cotiperating with themagazine or hopper initially receiving the coal. It hasbeen proposedheretofore to provide means forefl'ectingan even feed and distributionof the fuel, but

in prior instances it has been necessary to provide coal of special anduniform size to effect such even feeding.

The objectof my invention is to provide means for effecting an even feedand disreadily operated and available for-use with coal of any sizewithin reasonable limits.

These and otherfeatures forming the subject of my invention will befully pointed 1 out hereinafter, reference being had to the accompanyingdrawings, in which: A Figure 1, is a sectional elevation of a feeddevice for, furnaces, gas producers aiid the like, embodying myinvention; Fig. 2, is an enlarged plan view of the distributer employedin connection with my lmproved feed device; Fig. 3, is a sectional viewof the distributer on the line a a, Fig. 2; Figs. 4: and 5, aretransverse sectional views on'the lines 'bb" and c-c, respectively, Fig.2; Flg. 6, 1s a front elevation of one element 9f the distributingmember; F1g.'7, 1s a sectional 0 p I a I I plan vlew on the llne d.{l,Flg. 1-; 1 1g. 8.

is a sectional view similar to Fig.1 illusy trating another form ofstructure Il'lb()(lylug my invention, and Figs. 9 andlO, are,

respectively, a sectional elevation and plan view of a device tributingelement.

In the drawings herewith, 1 represents a magazine or hopper for thereception of fuel or other material introduced at the top of the same;such magazine being provided with a rotatable cover 2, to close or openthe top. of the hopper. The magazine or hopper carries a bracket 4receiving a bushing 5 which is mounted for rotation in said PatentedFeb. 21, 1911.

bracket and through said bushing a ver-- tically movable shaft 6 passes;said shaft being splined thereto by a feat-her 7 in order that it may beoscillated by movement imparted to said bushing simultaneously with itsvertical movement. The lower end of the shaft 6 carries a conicaldistributing member 8 of a special character, which may be connected tothe shaft by links 9. The magazine or hopper has a contracted outlet 10and the distributing members is preferably provided with an annularsurface 11 for contact with the lower edge 12 of said contracted outlet.

At the upper end of the shaft a thrust bearing 13 is provided forengagement with a collar 14 in which the end of the shaft- 1s free torotate, such collar being arranged to impart positive movement to theshaft when actuated in a vertical direction. The shaft. is maintained inthe raised position "with the distributingelement closed againstthe'lower mouth of the-hopper by means of aweighted lever 15.t-runnioned'to-said collar at 116 and fulcrumed at 17 to a link 18pi-votally connected at 19 to the bracket #1: said lever 15 having ahandle 20 whereby it maj be actuated. The bushing journaled in thebracket 4 is provided with a handle 21 whereby movement may be impartedto theshaft. 6 by the operator; such movement being simultaneous withthe lowering of the conical distributer carried by said shaft.

The conical distributer is of a novel construction, and inaddition tohaving means for throwing the material from its upper surface due tothecentrifugal action imparted to it by rocking the handle 21, ithas-apertures 22 through which a portion of the coal may bedischargedand an irreguimmargin with portions successively de-.

creasing in radial length. The apertures 22 are providedw1th acircumferential wall 23. and side walls 24- which form ribs eX- videdwith vanes or blades 25 of different same character, as those indicated'ried by a vertically dimensions disposed on its upper surface, whichare designed to divert the coal or other material as said member isrocked and as such material is dropped from thedistributer in a seriesof concentric paths it is caused to spread in a-subst-antially evenlayer in the gasproducer or furnace.

The structure shown in Fig. 8 is of subtantially the same character asthat shown in Fig. 1, except that provision is made for water coolingthe same throughout; the distributing member being also water cooled.For this, purpose, the distributing member is made hollow, as shown at26, and is carmovable hollow shaft 2-7 which may be actuated by means ofthe in Fig. 1, to lower the distributing memberand oscillate the same.The hollow shaft carrying the distributing member is provided with a cu30 atits upper end into which a cooling fluid ma .be introduced from apipe 31, suitably va ved at 32. From the cup 30 such fluid may pass tothe" hollow distributing member through a tube 33. As the distributingmember fills, the fluid risesin the hollow shaft outside the tube 33 andmay pass to a chamber 34' near the upper end of said shaft. and fromsaid chamber the fluid may overflow through a pi e 35 into a smallannular tank 36 suitably supported by the bracket 4:.' From this tank,the'fluid may overflow through apipe 37 into a tank38 surrounding thelower portion of the hopper or magazine, and from the latter it mayoverflow through a pipe 39 to a water receptacle 40 on top of thegasproducer or fornace.

I trated in Figs. -1 and '8, or

. The magazine or hopper may be agitated by the handle 21 connectedto'the bushing 5 through which the shaft slides, as illus- I may providea structure such as shown in consisting of a lever 41 with a pawl 42 forengagement witha ratchet 43 so as to im-.

part a continu'ously'rotative movement to the shaft G-and thence to thehopper from the intermittent doscillating movements of the lever 4:1.-The shaft is splined to the bushing, and the ratchet wheel may be keyedto the bushing, but in this instance these parts are in one piece, andthe lever is journaled on the bushing.
